Abstract
Background. Transcriptional dysregulation plays a critical role in the onset and development of malignant tumors. Employing gene dysregulation to forecast the change of tumors is valuable for cancer diagnosis. However, the prognostic prediction for HCC using combined gene models remains insufficient. Methods. The expression profiles of GSE103512 and TCGA-LIHC were downloaded. Gene Ontology (Go) was used to evaluate the overlapping differential genes (DEG) in TCGA and GSE103512. The core genes in the critical module most significantly related to HCC were obtained by WGCNA. Eight genes most significantly related to HCC and OS were identified by reweighted coexpression network analysis and Cox regression. Results. We selected eight genes, FZEB1, CDK1, RAD54L, COL1A2, ATP1B3, CASP8, USP39, and HOXB7. Moreover, we constructed an eight-gene model and forecasted the prognosis of HCC. ROC curve of the eight-mRNA prognostic model was screened out (
), suggesting that this model exhibited a good prediction performance. Survival analysis showed that the survival rate of patients in the high-risk group was significantly lower than that in the low-risk group. Conclusion. The eight-mRNAs model might forecast the OS of HCC patients and advance remedial decision-making.

Xiao C, Wang Y, Fan Y. Bioinformatics Analysis Identifies Potential Related Genes in the Pathogenesis of Intrauterine Fetal Growth Retardation. Evol Bioinform Online 2022; 18:11769343221112780. [PMID: 35923419 PMCID: PMC9340335 DOI: 10.1177/11769343221112780] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Accepted: 06/06/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Intrauterine growth retardation (IUGR) affects approximately 10% to 15% of
all pregnancies worldwide. IUGR is not only associated with stillbirth and
newborn death, but also the delay of cognition in childhood and the
promotion of metabolic and vascular disorders in adulthood. Figuring out the
mechanism of IUGR is rather meaningful and valuable. Methods: Datasets related to IUGR were searched in the Gene Expression Omnibus
website. Principal component analysis (PCA) was used for normalization.
Differential expressed genes (DEGs) were screened out using the ggpot2 tool.
DEGs were used to conduct Gene Ontology (GO) terms, Kyoto Encyclopedia of
Genes and Genomes (KEGG) pathways enrichment analyses, and protein-protein
interaction (PPI) analysis. IUGR related genes were searched in the OMIM
website to look for the intersection with the DEGs. The DEGs were analyzed
for tissue-specific expression by the online resource BioGPS. The results
were displayed through volcano map, Venn map, box plot, heat map, and GSEA
enrichment plots drawn by R language packages. Results: Eleven DEGs were screened out of 2 datasets. One hundred ninety-five genes
related to IUGR in OMIM were retrieved. EGR2 was the only intersection gene
that was found in both groups. Genes associated with placental tissue
expression include COL17A1, HSD11B1, and LGALS14. Molecular functions of the
DEGs are related to the oxidoreductase activity. The following 4 signaling
pathways, reactome signaling by interleukins, reactome collagen degradation,
Naba secreted factors, and PID NFAT tfpathway, were enriched by GSEA. Two
critical modules comprising 5 up-regulated genes (LEP, PRL, TAC3, MMP14, and
ADAMTS4) and 4 down-regulated genes (TIMP4, FOS, CCK, and KISS1) were
identified by PPI analysis. Finally, we identified 6 genes (PRL, LGALS14,
EGR2, TAC3, LEP, and KISS1) that are potentially relevant to the
pathophysiology of IUGR. Conclusion: The candidate down-regulated genes LGALS14 and KISS1, as well as the
up-regulated genes PRL, EGR2, TAC3, and LEP, were found to be closely
related to IUGR by bioinformatics analysis. These hub genes are related to
hypoxia and oxidoreductase activities in placental development. We provide
useful and novel information to explore the potential mechanism of IUGR and
make efforts to the prevention of IUGR.

Abstract
OBJECTIVE To investigate the placental morphology alterations and identify the clinical characteristics of women with polycystic ovary syndrome (PCOS) and their newborns. Pregnant women with PCOS (n = 12) and pregnant women without PCOS (n = 11) were recruited. Then, the placenta, maternal blood and cord blood were collected after delivery. DESIGN Clinical observational study. SETTING Not applicable. PATIENT(S) In the present study, pregnant women with PCOS and healthy pregnant women were recruited from the clinic of the Department of Obstetrics and Gynecology, First Affiliated Hospital, Heilongjiang University of Chinese Medicine, China, between February 2015 and October 2015. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) A proteomic analysis was performed on the placenta in women with PCOS and healthy women. RESULT(S) The maternal testosterone, androstenedione, dehydroepiandrosterone sulfate, free androgen index, cholesterol, apolipoprotein B, and apolipoprotein B/apolipoprotein A-I levels were significantly higher in the PCOS group than in the control group, and the offspring in the PCOS group had higher dehydroepiandrosterone sulfate, high-density lipoprotein, and cholesterol levels, when compared with the control group. The placenta in the PCOS group demonstrated infarction, calcification, and a greater intervillous space, when compared with the control group. A higher level of estrogen receptor-β protein was observed in the placenta of women with PCOS, when compared with women without PCOS. A total of 258 proteins in the placenta were identified to be significantly different, when the PCOS and control groups were compared, and fibronectin 1 exhibited the closest relationship with other differential proteins. CONCLUSION(S) The overexposure to hyperandrogenism and hyperlipidemia affects the functions of the placenta, which are associated with the development of metabolic disorders in newborns.

Abstract
OBJECTIVE To investigate the influences of aryl hydrocarbon (AHR), cytochrome P450 (CYP1A1), epoxide hydrolase 1 (EPHX1), and glutathione S-transferase P1 (GSTP1) genetic polymorphisms on small-for-gestational-age (SGA) infants. METHODS This nested case-control study (126 cases and 381 controls) was based on a prospective cohort study in Shanxi Province, China. We collected the general information of subjects using questionnaire and identified their single nucleotide polymorphisms by the MassARRAY genotyping platform. RESULTS The polymorphisms of CYP1A1 (rs4646421 and rs4646903) and EPHX1 (rs1051740) were significantly associated with SGA. Neonates of women with EPHX1 (rs1051740) and GSTP1 (rs1695) variant alleles were at a significantly increased risk of SGA compared with the reference group (OR = 5.26; 95% CI, 1.08-25.66), as were neonates of women with CYP1A1 (rs4646903) and EPHX1 (rs1051740) variant alleles (OR = 7.11; 95% CI, 1.55-32.62). The results of strata analysis by AHR (rs2282883 and rs17137566) showed that the associations between the polymorphisms of CYP1A1 (rs4646421 and rs4646903) EPHX1 (rs1051740), GSTP1 (rs1695) and SGA were of significance in women with variant heterozygous or homozygous genotype. CONCLUSIONS CYP1A1 (rs4646421 and rs4646903), EPHX1 (rs1051740), and GSTP1 (rs1695) genetic variances might increase the risk of SGA. AHR (rs2282883 and rs17137566) resulted in estimated effects varying across strata on CYP1A1 (rs4646421 and rs4646903), EPHX1 (rs1051740), and GSTP1 (rs1695).

Abstract
Acute kidney injury (AKI) is a common and life-threatening complication in critically ill neonates. Gestational risk factors for AKI include premature birth, intrauterine growth restriction and low birthweight, which are associated with poor nephron development and are often the consequence of pre-gestational and gestational factors, such as poor nutritional status. Our understanding of how to best optimize renal development and prevent AKI is in its infancy; however, the identification of pre-gestational and gestational factors that increase the risk of adverse neonatal outcomes and the implementation of interventions, such as improving nutritional status early in pregnancy, have the potential to optimize fetal growth and reduce the risk of preterm birth, thereby improving kidney health. The overall risk of AKI among critically ill and premature neonates is exacerbated postnatally as these infants are often exposed to dehydration, septic shock and potentially nephrotoxic medications. Strategies to improve outcomes - for example, through careful evaluation of nephrotoxic drugs - may reduce the incidence of AKI and its consequences among this population. Management strategies and updated technology that will support neonates with AKI are greatly needed. Extremely premature infants and those who survive an episode of AKI should be screened for chronic kidney disease until early adulthood. Here, we provide an overview of our current understanding of neonatal AKI, focusing on its relationship to preterm birth and growth restriction. We describe factors that prevent optimal nephrogenesis during pregnancy and provide a framework for future explorations designed to maximize outcomes in this vulnerable population.

Abstract
Intracranial aneurysm (IA) is a complex disease resulting in subarachnoid hemorrhage (SAH) due to a rupture. The average worldwide prevalence of this disease is about 2–5 %, with 50 % of them ending in death or neurological disorders of varying severity, with a high probability of recurrence of hemorrhage during the frst half of the year after rupture. Subarachnoid hemorrhage is annually registered in at least 18 thousand people in Russia. Associations of polymorphic variantsrs594942andrs11603042of theVEGFBgene in intracranial aneurysm development in the Volga-Ural region of the Russian Federation with the presence of the symptom complex of undifferentiated connective tissue dysplasia (uDST) and arterial hypertension (AH) were investigated. TheC* allelers594942andrs11603042of theVEGFBgene is a marker of an increased risk of IA as a whole (p= 0.025; χ2 = 5.052; OR = 1.32) in women as a whole (p= 0.001; χ2 = 10.124; OR = 1.70) and in comorbid state with uDCT (p= 0.002; χ2 = 9.501; OR = 2.34) and AG (p= 0.006; χ2 = 7.385; OR = 2.109). We found that the genotype *C*Cof locusrs594942of theVEGFBgene is a marker of an increased risk of intracranial aneurysm in general (p= 0.017; χ2 = 5.702; OR = 1.49) and among women in general (p= 0.0005; χ2 = 12.078; OR = 2.25) and with the symptomatic complex uCTD (p= 0.007; χ2 = 7.173; OR = 2.67) and AH (p= 0.010; χ2 = 6.471; OR = 2.51). We have obtained new results on the role of polymorphic variants of theVEGFBgene in the formation of intracranial aneurysm, taking into account the presence of the symptom complex uDCT and AH among the residents of the Volga-Ural region of Russia. A burdened comorbid background and the presence of undifferentiated connective tissue dysplasia and arterial hypertension can contribute to an increased risk of intracranial aneurysm, as evidenced by the results of our study.

Abstract
Herein, we present a 14-year-old patient with short stature (134 cm) referred from Paediatrics to our department for complementary evaluation since growth hormone (GH) treatment failed to show any improvement. He was born premature and small for gestational age. Genital examination classified the patient as Tanner I-II with small penis and testicular size for his age. Biochemical analyses revealed normal GH levels with low serum insulin-like growth factor-1 (IGF-1). Molecular diagnosis confirmed several mutations in IGF1R and IGFALS, and so he was diagnosed with Laron Syndrome or GH insensibility and treated with IGF-1 substitutive therapy. Learning points Evaluation of the GH/IGF-1 axis when short stature does not respond to conservative treatment must be included in the ordinary practice.Laron Syndrome real incidence should be calculated once undiagnosed cases arise, as treatment, due to lack of market, is unaffordable.Even when adulthood is reached, and no longitudinal growth can be achieved, still IGF-1 treatment in Laron Syndrome patients should be pursued as metabolic and protective derangements could arise.

Abstract
Proper function of the blood-testis barrier is pivotal to spermatogenesis. Synchronised action of matrix metalloproteinases (MMP) and their inhibitors (TIMP) is mandatory to maintain dynamic balance of the barrier. Therefore, the association of functional genetic variants of MMP-2, MMP-9 and TIMP-2 and male infertility was studied. A total of 416 infertile males and 421 healthy subjects were genotyped for 7 SNPs within MMP2, MMP9 and TIMP2 genes, along with the assessment of semen parameters (concentration, motility and morphology of spermatozoa). No association was observed between the studied genotypes and male infertility. However, higher sperm concentration was associated with TIMP2 rs8080623 C and rs2277698 T variants among infertile men, and with MMP9 rs17576 A minor allele in controls (p < .05). TIMP2 rs9900972 T and rs2277698 T allele were associated with higher percentage of morphologically normal spermatozoa among controls. MMP2 rs2285053 TT homozygous infertile patients presented higher percentage of spermatozoa displaying nonprogressive motility. Haplotype analysis revealed strong linkage disequilibrium between the studied loci (5 of 8 possible TIMP2 haplotypes, and 3 of 4 possible MMP2 and MMP9 were found). None of the haplotypes showed association with infertility. This study results suggest an association between MMP9 and TIMP2 SNPs with sperm parameters, but not infertility.

Abstract
Oxidative stress has been proposed as one of the causes involved in idiopathic fetal growth restriction (IFGR). However, the exact relationship between oxidative stress and IFGR is not understood. This study aimed at understanding the role of oxidative stress and antioxidant status in IFGR materno-fetal dyads and matched controls. 75 materno-fetal dyads with IFGR were enrolled with equal number of normal low risk controls. Malondialdehyde (MDA) levels were measured as marker of oxidative stress, while paraoxonase-1 (PON1) activity and total antioxidant capacity (TAC) of serum were measured as markers of antioxidant status. MDA levels were increased in both maternal and cord blood of IFGR neonates as compared to controls (p < 0.001). TAC of serum were found to be decreased in IFGR (both maternal and cord blood) as compared to controls (p < 0.001; p < 0.05, respectively). PON1 activity was found to be decreased in the IFGR mothers while it was found increased in IFGR cord blood (p < 0.01; p < 0.001)). IFGR is a state of increased oxidative stress. Decreased PON1 enzymatic activity in mothers is also associated with IFGR.

Abstract
Background Knee osteoarthritis (OA) is a complex disease involving both biomechanical and metabolic factors that alter the tissue homeostasis of articular cartilage and subchondral bone. The catabolic activities of extracellular matrix degradation products, especially fibronectin (FN), have been implicated in mediating cartilage degradation. Chondrocytes express several members of the integrin family which can serve as receptors for FN including integrins α5β1, αvβ3, and αvβ5. The purpose of this study was to determine whether polymorphisms in the FN (FN-1) and integrin genes are markers of susceptibility to, or severity of, knee OA in a Han Chinese population. Methods Two independent case–control studies were conducted on 928 patients with knee OA and 693 healthy controls. Ten single nucleotide polymorphisms (SNPs) of FN-1 and the integrin αV gene (ITGAV) were detected using the ABI 7500 real-time PCR system. Results The AT heterozygote in FN-1 (rs940739A/T) was found to be significantly associated with knee OA (adjusted OR = 1.44; 95% CI = 1.16–1.80) in both stages of the study. FN-1 rs6725958C/A and ITGAV rs10174098A/G SNPs were only associated with knee OA when both study groups were combined. Stratifying the participants by Kellgren-Lawrence (KL) score identified significant differences in the FN-1 rs6725958C/A and rs940739 A/T genotypes between patients with grade 4 OA and controls. Haplotype analyses revealed that TGA and TAA were associated with a higher risk of OA, and that TAG conferred a lower risk of knee OA in the combined population. Conclusions Our study suggests that the FN-1 rs940739A/T polymorphism may be an important risk factor of genetic susceptibility to knee OA in the Han Chinese population.

Abstract
PROBLEM Inflammatory biomarkers are associated with preeclampsia (PE) and poor fetal growth; however, genetic epidemiologic studies have been limited by reduced gene coverage and the exclusion of African American mothers. METHOD OF STUDY Cases and controls (N = 1646) from a pregnancy cohort were genotyped for 503 tagSNPs in 40 genes related to inflammation. Gene-set analyses were stratified by race and were followed by a single SNP analysis within significant gene sets. RESULTS Gene-level associations were found for IL6 and KLRD1 for term small for gestational age (SGA) among African Americans. LTA/TNF and TBX21 were associated with PE among European Americans. The strongest association was for PE among European Americans for an upstream regulator of TNF with RR = 1.8 (95% CI 1.1-2.7). CONCLUSION Although previous studies have suggested null associations, increased tagging and stratification by genetic ancestry suggests important associations between IL6 and term SGA for African Americans, and a TNF regulator and PE among European Americans (N = 149).

A failed vasodilation and angiogenic challenge from pregnancy onwards? Cytokine Growth Factor Rev 2013; 24:411-25. [PMID: 23800655 DOI: 10.1016/j.cytogfr.2013.05.008] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2013] [Revised: 04/30/2013] [Accepted: 05/21/2013] [Indexed: 12/25/2022]
Abstract
Preeclampsia is the major cause of maternofetal and neonatal morbi-mortality including intrauterine growth retardation, miscarriages and stillbirths. Inadequate vascular dilation and angiogenesis represent the crucial underlying defect of gravidic hypertension, denoting a failed response to the vasodilatory and pro-angiogenic challenge imposed by pregnancy, especially if multifetal. A similar pathogenesis appears involved in gestational diabetes. In this review we aimed to provide a hint on understanding the deeply involved angiogenic disorders which eventually culminate in utero-placental failure. The key players in these complex processes may be found in an intricate network of growth factors (GFs) and GF inhibitors, controlled by several vascular risk factors modulated by environment and genes, which eventually impact on early and late cardiovascular outcomes of mother and fetus.

Abstract
PURPOSE OF REVIEW Intrauterine growth restriction (IUGR) occurs when fetal growth rate falls below the genetic potential and affects a significant number of pregnancies, but still no therapy has been developed for this pregnancy disease. This article reviews the most recent findings concerning maternal characteristics and behaviours predisposing to IUGR as well as maternal early markers of the disease. A comprehensive understanding of factors associated with IUGR will help in providing important tools for preventing and understanding adverse outcomes. RECENT FINDINGS Maternal nutritional status, diet and exposure to environmental factors are increasingly acknowledged as potential factors affecting fetal growth both by altering nutrient availability to the fetus and by modulating placental gene expression, thus modifying placental function. SUMMARY Assessing nutritional and environmental factors associated with IUGR, and the molecular mechanisms by which they may have a role in the disease onset, is necessary to provide comprehensive and common guidelines for maternal care and recommended behaviours. Moreover, maternal genetic predispositions and early serum markers may allow a better and more specific monitoring of high risk pregnancies, optimizing the timing of delivery.
